Some of us have done tons of work to try to modernize and otherwise improve the site. Most/all of these changes have been small, "incremental" improvements. But there are impediments to making the kind of sweeping changes that most people envision.

I apologize for any offense or insult my comments caused!

I was thinking of the types of changes like "Why does it still use table-based layouts" or "Why is the CSS so grotty" or "Why can't you separate the templates from everything else?" which have the impediments you mention.

(Like you, I've also added some incremental improvements to the site, long ages ago.)
